Description

Satellite remote control instruction format design and coding management system and method

Technical Field

The invention relates to a satellite remote control instruction format design and coding management system, which is suitable for the overall design stage of a satellite or a spacecraft, is used for completing the remote control instruction format design and coding generation and management related to a satellite-borne information system, and belongs to the technical field of spacecraft electrical design.

Background

In the stages of satellite ground test, flight control, on-orbit test, operation and the like, different instructions are required to be arranged into code words on the ground according to a certain format and are sent to the satellite through a ground control center, so that the satellite can complete specified actions. In the same way as in the AIT test, the butt joint test and the flight control set, the format and the code of the satellite remote control command need to be provided for relevant units to be used as key input for carrying out subsequent work, and the correctness and the integrity of the code must be ensured.

In the early development stage of the satellite, a global designer of the satellite-borne information system (hereinafter referred to as global designer) clearly defines the classification, format and command mode (mainly a normal mode and an emergency mode) of the instructions of the whole satellite. Partial fields of the instruction code, such as a leader, a check bit and the like, are uniformly specified by an information general designer and are specified in the whole star instruction format specification file. The effective code words of the instruction codes are partially from different sources and are roughly divided into three types, one type is the code words completely determined by the design and allocation of the hardware contacts, the code words of the hardware instructions comprise most hardware instructions, the code words of the hardware instructions are directly related to the design and allocation of the hardware contacts, and when the design of the contact allocation is finished, the code words of the hardware instructions can be determined after the instructions and the hardware contacts are one-to-one bound. The second type is software instructions, independent of the contact assignment, that are provided by the associated software designer based on the software design state.

It can be seen that the input sources of the instruction formats and the encoding descriptions are numerous, different fields of the same instruction need to be input differently, and an information general designer needs to encode the whole star instructions one by one manually on the basis of fully understanding the format and the encoding description file and calculate the length and the check bits, so that the problems of large mechanical workload, long design period, high error probability, disordered version control and the like exist.

Detailed Description

The invention is further described with reference to the following figures and detailed description.

As shown in fig. 2, the present invention provides a satellite remote control command format design and coding management system, which includes a dictionary tool box, an interface tool box, a measurement and control tool box, and an output tool box.

The several toolboxes are described in detail below, respectively.

(1) Dictionary tool box

The dictionary tool box is used for summarizing and summarizing each field of the instruction and formulating generalized dictionary items used in instruction coding, wherein the generalized dictionary items comprise data field types, editing types (including drop-down box editing, text box editing, calculation formula editing and the like), variable attributes (whether variable or not) and the like, and the dictionary items are irrelevant to models.

Each data field type mainly has an associated option class, a calculation class, a user-defined editing class, a fixed code word class, an inheritable class and the like. The specific description is as follows:

a) associated options class

The associated option class data refers to data associated with the instruction parameters in the instruction parameter table or the hardware nodes in the contact information table, for example, the code/name of the instruction sending device, the code of the connector where the instruction is sent, the code/name of the module to which the instruction sending distribution belongs, the code/name of the contact to which the instruction sending distribution belongs, the code/name of the matrix sending row/column coding, the conventional instruction coding, and the code/name of the device to which the instruction belongs belong.

b) Computing class

The calculation-like data refers to data obtained by calculation. The method generally comprises three subclasses of length calculation, checksum calculation and code word processing calculation.

1) Length calculation

The configuration items of the length calculation class data comprise: calculating an initial value, calculating a range and calculating a unit. And (4) adopting a calculation formula to express. Wherein:

● calculate the initial value: refers to a value that increases or decreases in the result of the length calculation;

● calculate the range: defining a calculation range by taking fields as units in the current-stage format (not including sub-stages), wherein the left-most field is the first field and is sequentially ordered to the right;

● calculation units: the calculation result may be selected in units of word, byte and bit (1 word or 2 bytes or 8 bits).

Taking the instruction format shown in fig. 3 as an example, assuming that the type of the field c in the secondary instruction format 1.1 is a length calculation class, the calculation range can only be the secondary instruction format, and the length is the total length (calculated by word) -1 of the field a and the field b, then the expression is exemplified as follows: LEN (0+1)/16-1, where "0" represents the 1 st field of the current-level format, i.e., field a, "1" represents the 2 nd field of the current-level format, i.e., field b, "LEN (0+ 1)" represents the total bit length of field a and field b, the length of field a and field b is constrained to be an integer multiple of 16, and is not filled with 0, and "1" represents that 1 is subtracted from the above calculation result, i.e., the calculation initial value is "-1".

2) And (3) checksum calculation:

the check sum calculation class data comprises the following configuration items: calculating an initial value, calculating a range and calculating a type.

Wherein:

● calculate the initial value: refers to a numerical value that increases or decreases in the result of the calculation;

● calculate the range: defining a calculation range by taking fields as units in the current-level format (not including subsets), wherein the field at the leftmost side is the first field and is sequentially ordered to the right;

● calculation type: modulo two addition, odd check, even check, CRC check, XOR sum by fixed length (including XOR sum by word and byte).

3) Codeword processing calculation

The codeword processing calculation mainly refers to a codeword truncation operation, where the codeword truncation operation is to perform truncation processing on a codeword of a certain associated option class, and an truncation range (converted into binary) may be selected, for example: the code word in the encoding column of a certain instruction is '02181', and the truncation range is: 6-12, 02181 is first transformed into binary code word "00000010000110000001" and then the contents of 6bit to 12bit, i.e. "0100001", are intercepted.

4) Custom editors

The custom edit class is a code word provided by external input, and can be a custom variable code word with an indefinite length or a custom fixed code word with a fixed length. After the instruction format design is completed, when the code is generated, the field code word of the instruction is filled in the form by a software designer in the field with the type of the custom editing class, and then the field code word is imported into the system to obtain a complete instruction code table.

5) Fixed code word class

The fixed code word data is a data segment with fixed code words, the fixed code word data is manually filled by a user when an attribute configuration table is established, and the preset code words are automatically filled into corresponding fields by the measurement and control tool box when an instruction coding table is generated.

6) Inheritable classes

The inheritable class is a special data segment type used when the instruction format tree is established, the data segment defined as the inheritable class can be inherited by the next level of the instruction format, and the content of the inheritable class field is embodied in the format definition of the next level of inheritance. When generating the code, an instruction referencing an inherited parent instruction format should contain all field configurations or fixed codewords in the parent and higher formats.

(2) Interface tool box

The interface tool box is related to the type, according to an interface data sheet and/or a specification of the instruction sending equipment, a hardware instruction code word needing to be sent through a hardware contact of the instruction sending equipment is distributed to the contact of the instruction sending equipment, so that a mapping relation between the hardware instruction code word and the contact number is established, a distribution result is stored in a contact information table of the instruction sending equipment, an instruction code number in an instruction parameter table is related to the contact number of the instruction sending equipment, and further the mapping relation between the hardware instruction code word and the instruction code number is obtained.

The instruction parameter table format is shown in the following table:

the contact information table of the transmitting device is as follows:

For hardware instructions that need to be distributed through the contacts, after completing the instruction distribution, the following table is obtained:

therefore, in the database, the instruction code of the hardware instruction is associated with the code word of the hardware instruction, and an instruction coding configuration table of the hardware instruction is obtained:

(3) measuring and controlling tool box

And the measurement and control tool box is used for designing an instruction format, distributing a corresponding instruction format for each instruction in the instruction parameter table, obtaining instruction and format mapping, forming an instruction code configuration table to be coded, automatically designing the table according to the attribute or the instruction code configuration table corresponding to the instruction field, finishing the coding corresponding to the instruction field, generating a complete instruction code table and storing the complete instruction code table.

The measurement and control tool box is related to the model and comprises an instruction format design unit, an instruction format distribution unit and an instruction coding management unit. The details are as follows:

(3.1) instruction Format design Unit

The instruction format design unit is used for realizing the functions of instruction format design, instruction format preview, instruction format management and the like.

(3.1.1) instruction Format designer

The instruction format design is completed by an instruction format designer. The instruction format designer is integrated in an instruction format page of the measurement and control tool box, an instruction format tree of the type is built, after initialization is completed, the designer can be started to design and edit the format by selecting a certain instruction format, and the specific process is shown in fig. 4.

The format designer performs attribute design on each field of the instruction format in order from the upper bit (MSB) to the lower bit (LSB), forming an attribute design table. Adding data segments according to an externally input instruction in sequence, setting data segment attributes, wherein the data segment attributes comprise data field types, field configuration, names and lengths, and generating an instruction format.

The attribute design table is as follows:

	data field type	Field configuration	Name (R)	Occupy bit	Description of the invention
						Field
1	Subclass a
						Field 2	Subclass b
…

Data field type: the method mainly comprises six types of data field types, namely, a related option type, a calculation type, a user-defined option type, a user-defined editing type, a fixed code word type and an inheritable type which are defined in a dictionary toolbox. Each type has a subclass, and the type at the lowest level in the dictionary entry is selected.

And field configuration: the 'data field type' selects different subclasses, and has different field configuration methods, for example, selects 'associated option type-instruction type associated code', and the field configuration attribute is set by adopting different field configuration tables according to the selected data field type; for example, selecting "calculation class — checksum", the field is configured to design a calculation formula; for example, selecting "fixed codeword class," the field configuration directly fills out the codeword.

The field configuration includes two configuration parameters, one is a fixed parameter and the other is a variable parameter. For the first category, the values of the fixed parameters may be obtained directly from the field configuration table, i.e. the code words are filled in directly. For the second type, when the data field type is one of the associated option type or the custom edit type, the instruction encoding configuration table needs to be indexed according to a certain attribute of the instruction (such as an instruction code number, an instruction type, a sending device, and the like) to obtain a code word of the field of the instruction.

Assuming that the "data field type" of the field 1, the field 2, and the field 3 in the attribute design table is "instruction type association code", and for an instruction adopting this format, the actual code words of the field 1, the field 2, and the field 3 thereof respectively depend on the sending device of the instruction, the instruction type of the instruction, and the hardware contact occupied by the instruction in the instruction parameter table, the corresponding "field configuration" shall be the following field configuration table (see italic table):

the field configuration table simply defines how the field takes values, and the instruction encoding configuration table defines the corresponding actual code words (default to 16-ary) when the values are different names. Taking field 1 in the above table as an example, the "name" in the configuration sub-item list must be consistent with the sending device in the instruction parameter table, when generating the code word, the system reads the sending device corresponding to the instruction in the instruction parameter table, and indexes the instruction encoding configuration table (see italic form), and automatically fills the code word into the position of field 1.

Name: the name of the field indicates the meaning of the field, for example, a terminal address, an instruction type, instruction data, a check bit, and the like, and the name of each field is displayed in order from lower to higher when the instruction format is previewed. If the data segment is the associated option class, the measurement and control tool box configures the selectable data field type or the subclass thereof and the corresponding code word, the name of the data segment is the same as the name of the option configuration by default when the option configuration is selected in a pull-down mode, and the name is allowed to be edited.

Occupying bit positions: and filling the length of the field, wherein the unit is bit, and filling the maximum length if the length of the field is uncertain, namely the data field type of the field is the self-defined variable code of the self-defined editing class. The length of the code word generated finally is based on the actual filling length, for example, for a certain instruction format, the field is a self-defined variable code word, the length is 32 bits, the actual filling code word is 16 bits, and the length of the field in the finally generated instruction code is 16 bits.

(3.1.2) instruction Format Preview

On the instruction format page, the left side is the instruction format list and the right side is the format description and preview. Wherein the format specification allows specification of the instruction format in a chartlet and text manner. The instruction format preview includes the table header, word order, field meaning of the format, and the codeword that can be determined.

(3.1.3) instruction Format management

The command format management means that command formats of the same model are managed according to a tree structure of 'platform-model-each-level command format', when the command formats are established, an initial item should contain 'format names', 'format codes', whether to inherit the command formats and which parent-level command format to inherit, wherein the inheritance parent level should select from the established formats. Assuming that the instruction format of a certain model has three levels, the instruction format tree is shown in fig. 5. When the instruction format is established, because the satellite instruction format is relatively fixed, the inheritance of the contents of the satellite instruction code words in the same system is very strong, the existing format can be called from the instruction format libraries which are already finished by other models, and the repeated work is reduced.

As shown in fig. 3, if the high-level instruction format designs fields 1, 2, 3, 4, and 5, where the data field type of field 3 is "source data", the low-level instruction format chooses to inherit the parent attribute, and fields a, b, and c are designed, the complete instruction format of the low-level instruction format is field 1, field 2, field a, field b, field c, field 4, and field 5.

3.2 instruction Format Allocation Unit

And the instruction format distribution unit distributes a corresponding instruction format for each instruction in the instruction parameter table according to the design requirement on the instruction coding page to obtain the instruction and format mapping. After the instructions are screened out, the same instruction format is allocated to the instructions in batches through an index command sending mode, an instruction type, sending equipment and the like, the allocated instruction format can be deleted item by item or in batches on an instruction coding page, a certain type of instruction format is selected, and all the instructions allocated to the format can be checked.

After the instruction format allocation is completed, the following table is obtained:

3.3 instruction code management Unit

The instruction code management unit is used for realizing the functions of instruction code generation, instruction code preview, instruction code management and the like.

(5) Instruction code generator

The instruction code generator reads the code word source according to the instruction format distributed to the instruction, fills the code words in data fields one by one, and deletes the generated instruction codes one by one or in batch on the instruction code page.

The codeword sources are mainly in five categories:

1) the first type mainly aims at the data fields of the associated option type, obtains code word information from an attribute design table or an instruction coding configuration table corresponding to the instruction field after analyzing the attribute information and the contact distribution result of the instruction, such as an instruction sending mode, sending equipment, an instruction type and the like, and matches and fills the code word information in the corresponding field by combining the mapping relation established during instruction format design.

The second type mainly aims at the data field of the fixed code word type, when the instruction format is designed, the code word is defined for the data field according to the specific requirements of the model, all the instructions of the format are distributed, and the code word of the data field can be determined, so that for the data, the corresponding attribute design table is indexed to obtain the fixed code word, and the corresponding field is filled. For example, for the "hardware instruction" format, the "type identification" field is the fixed code word "A5A 5".

2) And the third type mainly aims at the data field of the custom editing type, and generates an instruction coding table after finishing the instruction format design through code words provided by external input, such as software instructions, part of fields in the coding are obtained according to the design result, but the fields of the type of the custom editing type have no code words, a software designer fills the code words of the field of the instruction in the table and then imports the code words into a system, and the fields are the code words filled by the designer directly.

3) And the fourth type mainly aims at the data field of the calculation type, obtains calculation results of length, checksum and the like according to the code words of other fields and the calculation formula of the field, and fills the calculation results in the corresponding field as the code words. The calculation formula of the calculation data field is predefined, when the code word changes, the calculation data field can be updated in real time, manual repeated calculation is not needed, and the encoding accuracy and the encoding efficiency are improved.

4) The fifth type is mainly aimed at the data field of the inheritable type and is filled in the field according to the encoding of the inherited instruction format.

For the related option class data field, when related attribute or contact information in other related forms changes, the system prompts that the format is allocated to the instruction, which causes the instruction code word of the corresponding field to change, and allows to select whether to keep the original code, if not, the original generated code is directly covered, if so, notes are allowed to be filled in for the newly generated code to distinguish, and whether to set the newly generated code as the main code is allowed to select.

For the calculation class data field, if the actual calculation result is not an integer number of words, the length field unit in the format preview is marked with red, and errors are reported when the code words are output. If the length calculation result is less than 0, then "error is reported". In addition, the calculation input should satisfy the corresponding type of algorithm limitation, such as the calculation range according to the fixed length exclusive or sum should be an integral multiple of the fixed length, and the fixed length should be equal to the length of the data segment, otherwise, the error is reported.

After finishing the generation of the instruction code, obtaining an instruction code table:

for each instruction format, a sub-page of the instruction code table displayed by fields can also be obtained at the same time, for example, for instruction format 1:

wherein:

1) subsystem, belonging equipment, instruction code, order mode, sending equipment, instruction name and instruction type: consistent with the instruction parameter table.

2) Format code number: the filling content should be consistent with the format code number defined in the instruction format.

3) Variable parameter length: variable length is automatically filled in by the system based on the sum of all field lengths with the "variable" attribute, expressed as X (m/n/../p) or X '-Y' (m '/n'/../p '-q'), in units of bit. X represents the total length, and if the total length is a range, X ' -Y ' represents a lower limit, and Y ' represents an upper limit. M, n, …, p, m ', n', … in parentheses are the lengths of the respective variable fields, and are separated by "/", and if there are variable fields of indefinite length and the length of the last variable field is denoted by p '-q', X '+ n' + … + p ', and Y' + n '+ … + q'. If the instruction format referenced by an instruction does not contain a variable field, the cell fills in "NA".

4) Variable parameter position: variable parameter location describes all locations with "variable" attribute fields, and the system automatically fills in based on the results of the command format design, starting with the location number at D0, MSB at D0, and bit. Expressed as Da-Db, Dc-Dd, …, corresponding to the variable parameter length expression X '-Y' (m '/n'/./p '-q'). Such as: D8-D16/D20-D23/…/D32-D39, wherein D8-D15 corresponds to a field with length m ', then m' is 15-8+ 1-8, and D32-D39 corresponds to a field with variable length p '-q', then the position is calculated according to the upper limit q 'of the variable length, i.e. p' is 39-32+ 1-8. The first bit of the parameter location should start from the first bit of the highest level format that the instruction format inherits.

For the variable parameters, for example, the code words start with D0:

1. the variable parameter has 3 variable fields, all of which are variable fields with invariable length

Wherein: x is 16, m is 8, n is 4, p is 4

2. The variable parameter has 3 variable fields, and the 3 rd field length is variable

Wherein: x '═ 16, Y' ═ 20, m '═ 8, n' ═ 4, p '═ 4, and q' ═ 8.

5) Remarks, notes are made for various special matters, such as: the non-encryptable instruction should be denoted as { non-encryptable }.

(6) Instruction encoding preview

The instruction encoding preview is used for checking the instruction encoding generated result in an instruction encoding preview page, wherein the word sequence is arranged according to the sequence of D0, D1 and D2 … Dn, and D0 is MSB. Either the "binary" display or the "hexadecimal" display may be selected, with the default display state being "binary".

According to the invention, the command format design and code generation result is converted into the two-dimensional table interface, and compared with the text description, a user can intuitively preview the command format and code.

(7) Instruction encoding management

Recording the change, if the change is determined, submitting examination and approval in a measurement and control tool box, selecting related users for examination and approval, locking the instruction code in the change by the current user, not changing other users, and unlocking after the examination and approval process is completed. Meanwhile, according to design requirements, fields in the instruction format are associated with corresponding instruction attributes and the contact information distributed by the instruction, when the relevant attributes or the contact information change, the change of the coding requirement is automatically prompted, data homology is guaranteed, and the problems of errors or omission and the like possibly caused by manual change are avoided.

(4) Tool box with output function

The output tool box sets filtering conditions on the basis of a complete instruction coding table according to an external instruction, screens the instructions according to the filtering conditions and the display conditions and the instruction sequence in the instruction parameter table, and generates and outputs an instruction coding file of the screened instructions.

Before the instruction codes are derived, filtering conditions such as a command sending mode, a command type and a command sending device can be set, the derived coding field range is set to be an effective code word or a full-frame code word, the derived code word is set to be displayed in a binary system or a hexadecimal system, and whether the code word is inserted by 8 or not is set. And indexing the format and the code corresponding to the instruction in the instruction coding page, and generating an instruction coding file according to the setting and the instruction parameter list sequence.

The end point and purpose of the whole workflow is to accomplish the management of the instruction encoding. The source of the command code can be roughly divided into two aspects, namely, internal input and external input, wherein the internal input mainly refers to a table obtained by internal processing such as a command code configuration table, and the external input is configured by a designer through an external import mode for a command format or directly for a code word. The design flow of the hardware code words is definite, the format is fixed, the sources of other non-hardware code words are complex, and the formats are various, so that an instruction format library can be established, the formats designed by a designer by using a format designer are effectively managed, for different instructions, only the design result in the format library is called, and the variable parameters and the code words in the instruction format are led in according to the template, and the complete instruction code words can be generated.

The invention provides another technical scheme that: a satellite remote control instruction format design and coding management method. As shown in fig. 2, the method comprises the steps of:

(1) classifying the instruction formats according to the use function of the information system of the actual satellite model and the design specification of the whole satellite and the types of the instructions, establishing an instruction format tree of a target model, naming and numbering the instructions of all levels of the instruction format tree, wherein the numbers of different instruction formats are unique. And storing the name, the model name, the serial number, the upper and lower level relation and the remark description information of characters or pictures of the satellite platform in the instruction format.

(2) Setting the data segment attribute of each field in the instruction format to form an attribute design table, wherein the data segment attribute comprises data field type, field configuration, name and length, so as to complete the instruction format design;

the instruction format is formed by combining various fields, and the design of the instruction format is actually a process of designing each field in the instruction format respectively. When designing the field, firstly, the data field type needs to be designed, and all the field types are classified into 5 categories according to the actual design requirement, including: the tool comprises an association option class, a calculation class, a custom editing class, a fixed code word class and an inheritable class, wherein the processing logic of the 5 classes is built in the tool. In the field type configuration, the definable parameters in the processing logic of the 5 types are configured on a configuration interface, and the configuration result of the parameters is stored in a field configuration table through an external instruction to form a field subclass, wherein the field subclass belongs to one of 5 large field types. And then, defining the name, the editing type, the related value of the editing type, the changeability, the interception expression and the remark of the newly added field subclass through field type configuration, carrying out information interaction with a field configuration table built in a background database through a tool interface after configuring the information on the interface, and storing all configuration information into the field configuration table.

According to the design constraint of an instruction interface, the constraint comprises an instruction response function of a single machine of an instruction receiving end, a hardware interface circuit form or a bus form, a bus protocol specification and the like, different instruction formats are designed respectively, the design mode is that bit is used as a minimum unit, each field in the instruction format is defined and is sequentially arranged according to a word sequence (D0 is MSB), a design result is stored in an attribute design table, and in the attribute design table, any field in the format can be added, deleted, edited and stored through an external operation instruction and is displayed on the design interface. The attribute design table contains the type, value, name, length and field description of the field, wherein the type of the field is selected from the stored field subclasses in the field configuration table, and the corresponding processing logic is also consistent with the configuration parameters defined in the field configuration table. In the design process, all information is required to be filled according to actual design requirements and is stored in an attribute design table.

After the format design is finished, according to preset logic, the information stored in the attribute design table is previewed on a design interface in a two-dimensional table form, the table comprises a WORD sequence, a bit position, a field name and a field length, and one WORD, namely 16 bits, is displayed in one line. The logical relationship is that, in the attribute design table, the fields are stored from top to bottom, the tool of the present invention can automatically read the upper and lower relationship of the fields, splice the fields into an instruction format according to the field lengths in the attribute design table, perform secondary cutting on the instruction format according to a WORD as a line, and display the instruction format from top to bottom according to the line unit, as shown in fig. 6. Meanwhile, according to the format after cutting, the conditions that two or more continuous WORDs belong to the same field are automatically combined, so that the condition that the preview format is too long and is difficult to manually interpret is avoided. The rule of merging is to display the line number in the form of a-b, where a is the merged head line number and b is the merged tail line number.

(3) Acquiring an instruction parameter table, and establishing a one-to-one mapping relation between instruction codes and instruction format codes in the instruction parameter table to form an instruction code configuration table to be coded; (ii) a The instruction parameter table is generated by collecting satellite instruction parameter information according to a predefined rule through external input, such as a single machine interface specification. The instruction code number in the instruction parameter table is unique and is used as a main key (which cannot be null or not repeated) of the instruction parameter table in the database.

the electrical connector contact information table is formed by collecting electrical connector contact information of each command transmitting device of the satellite according to a predefined rule through external input, such as a single-machine interface specification. The electric connector contact information table comprises equipment names, equipment codes, electric connector codes, names, electric connector models, contact numbers, types, signal contents, assigned information names, instruction codes and codes, wherein the instruction codes and the codes have one-to-one association relationship.

In practical application, according to the types, sending devices, receiving devices, use requirements, use scenes and the like of different instructions, one-to-one mapping relation is established between instruction codes and instruction format codes in an instruction parameter table, namely, the instruction format codes are filled in an instruction format column in the instruction parameter table through an external operation instruction, and after the operation is completed, all instructions needing to generate instruction codes belong to a certain instruction format.

(5) Automatically acquiring corresponding code words from an attribute design table or an instruction coding configuration table in a background database according to the instruction format, filling the code words in data fields one by one, completing coding corresponding to the instruction fields, generating a complete instruction coding table and storing the complete instruction coding table;

the parameter values obtained from the attribute configuration table include: field length, read-only values belonging to fixed code word class, computational expression and parameters of computational class.

The processing parameters obtained from the field configuration table are classified into two types, one being fixed parameters and the other being variable parameters. The values of the fixed parameters can be directly obtained from the field configuration table, and when the field type is one of the associated option class, the custom option class or the custom edit class, the values need to be obtained from the instruction code configuration table, the electrical connector contact information table or the externally input code configuration table associated with the field configuration.

An instruction code is generated according to a built-in processing logic based on an instruction format associated with the instruction and a processing parameter associated with the format. And storing the generated instruction codes in an instruction code table through the external instruction. According to the built-in processing logic, when all the parameters to be determined can be obtained in an attribute configuration table, a field configuration table, an instruction coding configuration table, an electric connector contact information table or an externally input coding configuration table according to the corresponding main key incidence relation, the parameters are brought into the processing logic, specific code words of each field can be obtained, and then the code words of each field are spliced according to the field sequence in the instruction format corresponding to the instruction, namely the sequence stored in the attribute design table, so that the generation of the instruction code words is completed. When the parameters required by the complete processing logic cannot be obtained in the attribute configuration table, the field configuration table, the instruction code configuration table, the electric connector contact information table or the externally input code configuration table according to the corresponding main key incidence relation, the generation of the instruction code fails, the steps are returned to completely supplement the corresponding parameters, the corresponding parameters are stored in the corresponding table of the database, and the code is generated again.

When the same instruction code is used for generating the instruction code for multiple times, if the code generation is successful, comparing whether the code corresponding to the instruction code as the main key in the instruction code table exists or not and the instruction code is completely the same, and if the code is completely the same, not storing the generated code in the instruction code table. And when the completely same codes corresponding to the main key with the instruction code number are not found, storing the codes generated at this time in an instruction code table.

When the instruction codes are displayed, the instruction codes meeting the conditions can be inquired by taking the instruction codes as main keys to screen different search conditions in the instruction parameter table and the instruction code table. And on the instruction unit preview interface, the instruction code which is successfully generated last time is displayed by default, so that the quick query is facilitated. If a plurality of instruction codes correspond to the same instruction code, the main code can be set through an external instruction, namely, a main code mark is filled in the rear column of the instruction codes in the instruction code table, and the instruction codes set as the main codes are displayed on an instruction unit preview interface in a default mode.

The parts of the present invention not described in detail are common general knowledge in the art.
